The 2006 Idaho Vandals football team represented the University of Idaho during the 2006 NCAA Division I FBS football season. Idaho competed as a member of the Western Athletic Conference (WAC), and played their home games in the Kibbie Dome, an indoor facility on campus in Moscow, Idaho. The Vandals were led by Dennis Erickson, hired following the departure of Nick Holt for an assistant's position at USC in February 2006. Erickson was previously the head coach of the Vandals from 1982-85, his first collegiate head coaching position.
